Aerodactyl, an extinct Flying Pokémon. Its hard fangs suggest that it was a carnivore. Its sharp claws were probably used to capture prey.

Aerodactyl is one of the prehistory fossil Pokemon from Gen I, revived from Old Amber. Unlike Kabuto and Omanyte though, Aerodactyl doesn’t evolve. And as of Gen V, is one of the few Gen I Pokemon still not to have an evolutionary relative.
Aerodactyl is fast, and has a lot of Attack. Unlike most Rock types that have lots of Defense, Aerodactyl’s defense is pretty low. Appearance-wise, it’s based on a dinosaur, with pterodactyl’s body and probably T-Rex’ head. I never realized until now that its jaw is huuuge.
